Steam Link device pixelated only on GPD Win Max 2020, so bad image quality

[MaiKai]

Hi guys,

I've got a Steam Link device connected to my TV and it's working fine with a mini desktop PC.

I was trying today to connected to my GPD Win Max 2020 (gaming windows handheld) and the big screen image on my TV is really really bad, even the static landing page is pretty unreadable. All network connections and speeds are fine, as the mini PC has the same and the image is really clear.

I've tried changing settings in the Steam Link device or steam app on GPD Win, as well as resolution in both devices but nothing seems to improve it.

After some further testing, tried the Steam Link device with:

* 3 TVs: LG, Samsung, Toshiba

* 2 laptops, 1 miniPC, the GPD Win 2020

The only combination that doesn't work is the GPD Win with any of the 3 TVs (same bad quality as soon as it launches). All other combinations are fine, any other laptop/miniPC with any TV brand, so there's something strange on the way this GPD Win interacts with the Steam Link, but I cannot figure it out.

Any idea, pls let me know and I'll give it another go 'cos the GPD Win is the one that practically, I'd like to have working.

This is how bad it currently looks:
